We present new ages and abundance measurements for the pre-main-sequence star PZ Telescopii (more commonly known as PZ Tel). PZ Tel was recently found to host a young and low-mass companion. Such companions, whether they are brown dwarfs or planetary systems, can attain benchmark status by detailed study of the properties of the primary, and then evolutionary and bulk characteristics can be inferred for the companion. Using Fibre-fed Extended Range Optical Spectrograph spectra, we have measured… 

First spectroscopic observations of the substellar companion of the young debris disk star PZ Telescopii

Context. In 2010 a substellar companion to the solar analog pre-main sequence star PZ Tel and member of the approximately 12 Myr old β Pic moving group was found by high-contrast direct imaging

New observations of the PZ Tel system, its substellar companion and debris disc⋆

We present follow-up high-contrast imaging data of PZ Tel B, the substellar companion of a solar analogue pre-main-sequence star and member of the approximately 12-Myr-old β Pic moving group. Between

Detection of Hα emission from PZ Telescopii B using SPHERE/ZIMPOL

Hα is a powerful tracer of accretion and chromospheric activity, which has been detected in the case of young brown dwarfs and even recently in planetary mass companions (e.g. PDS70 b and c). Hα

Astrometric follow-up observations of directly imaged sub-stellar companions to young stars and brown dwarfs

The formation of massive planetary or brown dwarf companions at large projected separations from their host star is not yet well understood. In order to put constraints on formation scenarios we

MIRACLES: atmospheric characterization of directly imaged planets and substellar companions at 4–5 μm

The circumstellar disk of PDS 70 hosts two forming planets, which are actively accreting gas from their environment. The physical and chemical characteristics of these planets remain ambiguous due to

First light of the VLT planet finder SPHERE II. The physical properties and the architecture of the young systems PZ Telescopii and HD 1160 revisited

Context. The young systems PZ Tel and HD 1160, hosting known low-mass companions, were observed during the commissioning of the new planet finder of the Very Large Telescope (VLT) SPHERE with several

Spectroscopic confirmation of M-dwarf candidate members of the Beta Pictoris and AB Doradus Moving Groups

Optical spectroscopic observations are reported for 24 and 23, nearby, proper-motion-selected M-dwarf candidate members of the Beta Pictoris and AB Doradus moving groups (BPMG and ABDMG). Using

Direct Imaging discovery of a second planet candidate around the possibly transiting planet host CVSO 30

We surveyed the 25 Ori association for direct-imaging companions. This association has an age of only few million years. Among other targets, we observed CVSO 30, which has recently been identified

On the age of the β Pictoris moving group

Jeffries & Binks (2014) and Malo et al. (2014) have recently reported Li depletion boundary (LDB) ages for the {\beta} Pictoris moving group (BPMG) which are twice as old as the oft-cited kinematic

A dusty M5 binary in the β Pictoris moving group

We report the identification of a new wide separation binary (LDS 5606) in the ~20 Myr-old beta Pic moving group. This M5+M5 pair has a projected separation of 26'', or ~1700 AU at a distance of 65



Direct detection of a substellar companion to the young nearby star PZ Telescopii

Aims. We study the formation of substellar objects (exoplanets and brown dwarfs) that are companions to young nearby stars. Methods. With high-contrast AO imaging obtained with NACO at ESO VLT, we


We report the discovery of a tight substellar companion to the young solar analog PZ Tel, a member of the β Pic moving group observed with high-contrast adaptive optics imaging as part of the Gemini

Chromospheric activities and kinematics for solar type dwarfs and subgiants : analysis of the activity distribution and the AVR

Aims. In this work we present chromospheric activity indices, kinematics, radial-velocities, and rotational velocities for more than 850 FGK-type dwarfs and subgiant stars in the southern hemisphere

Discovery of a Wide Substellar Companion to a Nearby Low-Mass Star

We report the discovery of a wide (135 ± 25 AU), unusually blue L5 companion, 2MASS J17114559+4028578, to the nearby M4.5 dwarf G203-50 as a result of a targeted search for common proper motion pairs
